 3## Philosophy
 4
 5Zed aims to collect only the minimum data necessary to serve and improve our product.
 6
 7Data sharing is opt-in by default. Privacy is not a setting to toggle—it's the baseline.
 8
 9As an open-source product, we believe in maximal transparency, and invite you to examine our codebase. If you find issues, we encourage you to share them with us.
10
11Zed, including AI features, works without sharing data with us and without authentication.
